Amazon has the first version of InnocentVolume 1 available now. It should also be available at conventions, specialty stores, etc.
The second version will have a Tony De Zuniga cover and is available from King Tractor Press in November Diamond Previews (next month). If you're a big fan of Tony's (like I am) then get your store to preorder it. This version should be pretty limited, maybe 1000 or so. It won't be around long.
If anyone wants to try and get this version at your comic book store, the Diamond Previews code is NOV073695. They'll need that to make sure they get some copies.
